Physical protector

ABSTRACT

A physical protector has a bag member ( 10 ) formed of gas-barrier seal members ( 1,2 ) different in deformability, and a valve (a) by which an air passage is formed by exerting a pushing force to the seal members ( 1,2 ) to elastically deform the seal members and closed by releasing the pushing force to resume the original shape of the seal members. The physical protector is attached to physical parts such as the human trunk or limbs and inflated by operating the valve (a) to introduce air into the bag member ( 10 ), thus protecting the physical parts. Since the air can be arbitrarily introduced into or discharged from the bag member by operating the valve (a), the protector can be used repeatedly. The valve (a) is made flat and compact so as not to give the user an unpleasant feeling.

TECHNICAL FIELD

This invention relates to a physical protector having an inflatable bagmember with a small and simple vent valve which can be fittingly worn onor around various parts of the human body to conveniently protect them.

BACKGROUND ART

A variety of physical protectors for protecting the parts of the humanbody, including the trunk, arms and legs, have been used in medical,sports and other various fields.

One of the physical protectors is a chest pad formed by covering a padbase formed of elastic material such as foamed urethane, and has acurved surface fit for the chest with a soft material such as cloth.This chest pad has a commonly acceptable size so as to be generallyfitted to a human's chest with an average physique.

On the other hand, an elastic supporter which is formed by weavingelastic strings into a cylindrical texture of a befitting length is usedfor protecting the arms and legs. Since differences among individuals insizes of the human's wrist, arm and ankle are not noticeable,preparation of at least three supporters of large, medium and smallsizes may suffice for every person.

Thus, it may be useful to prepare physical protectors of different sizesfit for every person different in physique. However, the irrationalityof having many protectors of different sizes ready for various users hasbeen pointed out.

Furthermore, the size and shape of the chest pad as noted above are notcompletely conformable to those individuals different in physique.Therefore, when the chest pad of this sort is put on the chest of a manwith his clothes on, it will be uncomfortable to wear in most cases.Although the chest pad has generally the pad base as a core formed ofelastic material such as foamed urethane, it cannot be closely fitted tothe chests of all men, and therefore every man does not always feelcomfortable and cannot be protected completely.

The inventor of the present invention has proposed arm and fingerprotective holders each formed of a bag-shaped flat wrapping member inJapanese Patent Application Disclosure No. HEI 6-239268(A). The flatwrapping member of the proposed holder is provided with a vent valve andinflated with air introduced through the vent valve in a state woundaround the arm or finger, thus protecting the arm or finger.

The vent valve on the wrapping member of the aforesaid holder is formedby boring a small hole in a membrane of the wrapping member and sealingthe hole with an adhesive seal upon introducing air into the bag-shapedwrapping member through the hole. However, the vent valve of thisstructure makes it impossible to subtly control the expansion of thewrapping member. Moreover, the adhesive seal is used with the intentionof using the holder repeatedly, but the vent valve can neither endurerepeated use nor discharge the air efficiently.

In general, the vent valve of this type has a complicated structureincluding a valve body for performing the opening and closing operationsand a spring member for urging the valve body in one direction. Thus,this complicated vent valve mounted on the protective device entails astructural disadvantage such that it makes the protective devicecomplicated and bulky, although the protective device itself should besimple in structure and easy to handle.

A simple check valve may possibly be assembled in an air pipe to formanother vent valve. However, the vent valve also makes the protectivedevice thick and bulky, and besides, it is too hard to wear comfortably.

SUMMERY OF THE INVENTION

The present invention was made to remedy the drawbacks suffered by theconventional physical protectors mentioned above and has an object ofproviding a physical protector which is simple and compact in structure,has excellent durability, and is provided with a vent valve capable ofperforming selective introduction and release of air.

Another object of the present invention is to provide a physicalprotector which can be conformably fitted to an object to be protected,thereby suitably protecting the object.

Still another object of the present invention is to provide a physicalprotector capable of effectively protecting not only the human body andlimbs, but also various articles and commodities.

To attain the objects described above according to the presentinvention, there is provided a physical protector comprising gas-barrierseal members which are different in deformability, a valve which isopened by elastically deforming the seal members with a pushing force toform an air passage and closed by releasing the pushing force to resumethe original shape of the seal members, thus closing the air passage,and a bag member formed of sheet-like gas-barrier membranes so as to beattached to the human body or limbs. The valve is mounted onto the bagmember so as to open or close the bag member.

The valve is opened by utilizing the deformability of the seal membersto thereby let air in the bag member through the air passage, thusinflating the bag member with the air. The bag member thus inflated isworn on a part of the human body. When the valve resumes its originalshape, the air passage is closed. Therefore, by controlling the pushingforce exerted on the seal members, the inflation of the bag member canbe regulated to the desired condition. The discharge of the air from thebag member is accomplished by pressing the seal members to open the airpassage and then pressing the bag member.

The seal members may be made of soft and rigid seal materials. Since twosoft and rigid seal members of different kinds are different indeformability, a void is defined between the seal members to open theair passage when elastically deforming the seal members and closed whenelastically restoring the seal members due to the difference indeformability between the soft and rigid seal members.

The soft seal member noted above may be made of a film sheet, and therigid seal member may be made of a thick sheet having a desiredthickness. The seal members have vent holes at different positions,respectively, and are laid one on top of another and closely in surfacecontact with each other. Thus, the void through which the vent holesformed at different positions in the seal members are connected isdefined between the rigid and soft seal members to secure the airpassage. Since the rigid and soft seal members are laminated as notedabove, the air passage assumes its closed state under a normalcondition, thus fulfilling the function of a valve.

As another way, on the top of an elastically deformable rigid memberhaving a spherical surface with a central protrusion, a soft memberhaving a similar spherical surface may be closely placed, thusconstituting the seal members. With this structure in which the softseal member is elastically supported by the central protrusion of therigid seal member, the air passage defined between the seal members canbe securely sealed.

Otherwise, the soft seal member may have a vent hole in its centralportion, and the rigid seal member may have a vent hole in itsperipheral portion. In this embodiment, by depressing the rigid sealmember with a pointed tool or the like through the central vent hole inthe soft seal member, the void is formed between the seal members toenlarge the air passage. By pulling out the pointed tool, the rigid sealmember regains its original shape, thereby closing the vent hole boredin the peripheral portion of the rigid seal member. Thus, the functionof a valve can be fulfilled as well.

The soft seal member may be provided with elongated vent holes extendingfrom the central portion toward the peripheral portion of the sealmember, and the vent hole formed in the rigid seal member may be locatedapart from the elongated vent holes. With this structure, by depressingthe portion of the soft seal member in which one of the elongated ventholes is formed with a finger, a void is formed between the soft sealmember and the rigid seal member. Simultaneously, the remainingelongated vent holes formed in the portions of the soft seal member towhich the depressing force is not applied are open to form air passages.When the depressing force is released, the peripheral portion of therigid soft member first elastically restores its original shape to causethe peripheral portion of the rigid seal member in which the vent holesare formed to be brought into intimate contact with the soft sealmember, consequently fulfilling the function of a valve.

The rigid seal member may be provided with a support column extendingdownward from the lower surface of the rigid seal member. By depressingthe rigid seal member, the bag member is pushed down through the supportcolumn to widen the opening of the bag member.

The soft seal member may have a substantially H-shaped vertical crosssection so as to serve as a valve body to be set in a fitting hole whichis formed in the rigid seal member as a sleeve-like valve seat. Thevalve body is elastically deformed to secure the air passage betweenitself and the fitting hole in the valve seat. According to this, thesoft seal member is elastically deformed to form the air passage betweenthe soft seal member and the rigid valve seat.

Or again, the soft seal member may have a substantially H-shapedvertical cross section so as to serve as a valve body to be set in afitting hole which is formed in the rigid seal member as a sleeve-likevalve seat. The valve body is elastically deformed by operating a rotarypress means to secure the air passage between itself and the fittinghole in the valve seat. With this embodiment, by rotating the rotarypress means to depress the soft valve body, the soft seal member iselastically deformed to form the air passage between the soft sealmember and the rigid valve seat.

As a countermeasure, the rigid seal member may have a substantiallyH-shaped vertical cross section so as to serve as a valve body to be setin a fitting hole which is formed in the soft seal member as asleeve-like valve seat. The valve body is elastically deformed to securethe air passage between itself and the fitting hole in the valve seat.According to this, the rigid seal member is elastically deformed to formthe air passage between the rigid seal member and the soft valve seat.

The soft seal member may be formed into a valve body having a taperedbase portion so as to have a substantially H-shaped vertical crosssection as a whole, and the rigid seal member may be formed into asleeve-like valve seat having a tapered fitting hole. By depressing thevalve body to slide the valve body, an air passage is formed between thebase portion of the valve body and the fitting hole of the valve seat.According to this, by sliding the valve body along the tapered face onthe fitting hole of the valve seat, a void is formed between the valvebody and the fitting hole of the valve seat, and by bringing the valvebody and the valve seat into close contact with each other, sealingbetween the fitting hole and the base portion can be achieved.

The soft seal member may be provided with a pump for pressurizing fluidin the air passage. Furthermore, a watertight cap may be disposed on apart of the seal member to increases the water resisting property of thebag member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The embodiments of a physical protector according to this invention willbe described hereinafter with reference to the accompanying drawings.

FIG. 1 through FIG. 3 shows a first embodiment of a valve provided onthe physical protector according to this invention.

The valve a in this embodiment comprises one seal member 1 which isrelatively soft and thin and has a spherical surface, and another sealmember 2 which is relatively rigid and thick and overlaid in layers withthe soft seal member. Both seal members 1 and 2 are made of gas-barriersheet material, i.e. synthetic resin such as silicone and polypropylene,and artificial or natural rubber. The layered seal members are made byvacuum forming in the form of a spherical protrusion and have an elasticrecovery property with respect to a depressing force. It is desirablethat one seal member 1 has a thickness of about 0.01 mm to 1 mm, and theother seal member 2 has a thickness of about 0.5 mm to 3 mm.

The seal members 1 and 2 have vent holes 11 and 21 which are placed atdifferent positions so as to close each other when the seal members arelaminated. The surfaces of the laminated seal members 1 and 2 aredesired to be planished so as to be brought into intimate contact witheach other with great strength.

The vent hole 11 is formed in a round shape in one seal member 1 toallow fluid G such as air to pass therethrough and placed at the centerof the seal member. The seal member 1 has a curved peripheral rim 12.The elongated vent holes 21 are formed radially in the seal member 2 andslightly displaced from the center toward the periphery of the sealmember. The seal member 2 has a curved peripheral rim 22. Both sealmembers 1 and 2 are bonded along the rims 12 and 22 to a bag member 10by high-frequency welding or with adhesive, but the surfaces except therims 12 and 22 are not intimately sealed and in mere contact with eachother.

According to this embodiment, both seal members 1 and 2 made of therespective materials as noted above are different in elastic recoveryproperty. Thus, one seal member 1 is airtightly bonded with the otherseal member 2, so that the vent holes 11 and 21 are stopped by theintimately connected seal members 1 and 2.

By inserting a pin-like tool into the vent hole 11 of one seal member 1to depress the other seal member 2 as shown in FIG. 3, the other sealmember 2 is deformed, but the seal member 1 is little deformed. As aresult, an air passage 3 is secured between both seal members 1 and 2 toallow the fluid G to flow into or out of the bag member 10 through anopening 105. Likewise, when releasing the depressing force exerted onthe laminated seal members 1 and 2, the air passage 3 is formedtherebetween due to the difference in elastic deformability between theseal members.

Therefore, although the valve thus constructed is very simple andcompact, the air passage 3 for the fluid G can be reliably opened orclosed. Furthermore, since the laminated seal members 1 and 2 are notembrittled even if they are repeatedly deformed, the valve excels indurability. Besides, the rims 12 and 22 of the both seal members 1 and 2bring about the effect of maintaining the shape of the overall valve andfunction as a stopper for retaining the valve on various devices.

The rims 12 and 22 are basically provided on the valve of the firstembodiment, but are not absolutely necessary to this invention. Althoughnot shown in the accompanying drawings, the portions corresponding tothe rims of the seal members may be flat and confronted by the bagmember 10 to widen the area on which the bag member 10 and the valve aare disposed. Moreover, the number and shape of the vent holes 11 and 21are by no means limitative as long as the vent holes formed in therespective seal members do not coincide with each other.

FIG. 4 and FIG. 5 show a second embodiment of a valve for use in aphysical protector of the present invention.

On one of the mating surfaces of the laminated seal members 1 and 2, anannular small ridge 211 is formed. The small ridge in the illustratedembodiment is formed around the vent hole 21 bored in the seal member 2.In this embodiment, the mating surfaces of the seal members are in closecontact with each other to mutually close the vent holes in an ordinarystate. However, when the vent holes are opened to let in the air or thelike, the mating surfaces of the seal members can easily be separated towiden the air passage due to the small ridge 211, thereby facilitatingthe flowing of air or the like. Though not shown, the small ridge may beformed on the mating surface of the seal member 1 around the vent hole11.

Instead of the aforenoted small ridge 211, a combination of an O-ring111 and an O-ring receiving groove 212 can be used as shown in FIG. 5.The O-ring 111 is bonded to the periphery of the vent hole 11 of theseal member 1 with adhesive. The O-ring receiving groove 212 is formedin the portion of the other seal member 2, which is opposite to the venthole 11.

FIG. 6 shows a third embodiment of a valve assembled in a physicalprotector according to this invention, in which the shape relationbetween the seal members is reverse to the first and second embodiments.

The valve a in this embodiment subsides in the bag member 10 so as notto form a protrusion on the bag member 10. According to such a valvestructure, the protector can be worn without feeling an unpleasantsensation.

FIG. 7 through FIG. 9 shows a fourth embodiment of a valve for use in aphysical protector of the invention.

The seal member 1 has split-shaped vent holes 13 extending radially fromthe center toward the periphery of the seal member. Although the ventholes 13 in this embodiment extend in three radial directions, thenumber of the vent holes and the direction in which the vent holesextend are not limitative. The other seal member 2 has round vent holes23 placed at positions displaced from the center of the seal member 1and the split-shaped vent holes 13 formed in the seal member 1. The sealmember 2 further has a flange 24. This flange 24 extends verticallyoutward from the peripheral edge of the seal member.

According to this embodiment having the aforesaid structure, the ventholes 13 and 23 are mutually closed with the seal members similarly tothe first embodiment. By pushing down one tongue piece formed betweenthe adjacent vent holes 13 of the seal member 1, an air passage 3 isformed between the other tongue pieces of the seal member 1 and the sealmember 2 which is depressed with the tongue piece pushed down, as shownin FIG. 8 and FIG. 9, thus permitting fluid G to pass therethrough.

This embodiment brings about other operations and effects similar tothose brought about by the first embodiment. The flange 24 of the sealmember 2 has the effect of maintaining the shape of the overall valve.As a countermeasure, it is possible to form the vent holes 23 in theseal member 1 and the split-shaped vent holes 13 in the other sealmember 2.

FIG. 10 shows a fifth embodiment of a valve for use in a physicalprotector of the invention, in which a support column 25 is provided ona central portion of the inside of the seal member 2 of the aforenotedfourth embodiment.

According to this embodiment, the shape of the overall valve can bemaintained by the support column 25, so that the seal member 2 isprevented from being deformed unnecessarily. By depressing the valve,the support column 25 is thrust into the opening in the bag member 11,thereby facilitating the flowing of the air therethrough. Otheroperations and effects are the same as those of the aforesaid fourthembodiment.

FIG. 11 through FIG. 13 show a sixth embodiment of a valve for use inthe physical protector of the invention, which comprises one seal member4 formed of relatively soft synthetic resin in the shape of a valvebody, and another seal member 5 formed of relatively rigid syntheticresin in the shape of a valve seat.

The seal member 4 comprises a thin depressing plate 42 with vent holes41, a conical leg portion 43 extending from the depressing plate 42, anda bottom plate 45 with a protrusion 44 confronting the depressing plate42 astride the leg portion 43. Thus, the seal member 4 has asubstantially H-shaped vertical cross section as illustrated. The otherseal member 5 is formed in a sleeve for accommodating the seal member 4,and comprises a step portion 51 with which the depressing plate 42 isengaged, a fitting hole 52 serving as an accommodating hole forreceiving the largest part 431 of the aforesaid leg portion 43, and aflat flange 53 projecting outward.

According to this embodiment, the overall valve is made thin so that thebag member 11 can be engaged with an outer peripheral portion 532 andthe flange 531 of the other seal member 5. In the assembled state of theboth seal members 4 and 5, the largest part 431 of the leg portion 43and the fitting hole 52 are fitted in a tapering state to thereby closethe air passage 3. At that time, the protrusion 44 on the bottom plate45 is in contact with a bottom surface 533 of the other seal member 5 toclose the air passage 3. By pushing down the depressing plate 42 of theseal member 4, only the seal member 4 is deformed without deforming theother seal member 5. As a result, the largest part 431 of the legportion 43 and the fitting hole 52 are disengaged, and simultaneously,the protrusion 44 and the bottom surface 533 are disengaged,consequently opening the air passage 3.

The protrusion 44 of the seal member 4 has a function of preventing thebottom plate 45 from touching the other seal member 5. The otheroperations and effects are the same as those of the first embodiment.

FIG. 14 through FIG. 17 show a seventh embodiment of a valve for use ina physical protector of the invention, in which the depressing plate 42in the aforenoted sixth embodiment is provided on its central portionwith a projection 421.

This embodiment makes use of a home vacuum cleaner 2000, so as to attacha suction hose 2001 of the cleaner to an adapter 3000 to forciblydischarge fluid G, as shown in FIG. 14 and FIG. 15. The adapter 3000 hasa projection receiver 3001 having a function of depressing the aforesaidprojection 421, a retaining portion 3002 for the suction hose 2001, anda vent hole 3003 for connecting the projection receiver 3001 to theretaining portion 3002.

The vent hole 41 in the seal member 4 is closed with a screw cap 4000 tobe attached to the united seal members 4 and 5, as shown in FIG. 16 andFIG. 17, thus improving its sealing property. Furthermore, since theprojection 421 rises, handling of the valve is not spoiled even when thescrew cap 4000 is attached to the united seal members 4 and 5.

FIG. 18 and FIG. 19 show an eighth embodiment of a valve for use in aphysical protector of the invention in which relatively soft syntheticresin seal member 4 having a substantially H-shaped vertical crosssection in the aforementioned sixth embodiment is provided on its uppersurface with a projection 42′.

According to this embodiment, the depressing plate 42 in the sixthembodiment can be lifted up by using the projection 42′, therebydeforming the seal member 4 upward inversely to the sixth embodiment, toopen the air passage 3. Thus, the air passage 3 is reliably opened bythe operation of the projection 42′. The valve can be steadily fixedonto the bag member 10 by sharpening the outer peripheral edge of theseal member 5 so as to have the seal member ingrown into the bag member.

FIG. 20 and FIG. 21 show a ninth embodiment of a valve for use in aphysical protector of the invention, in which the relatively soft sealmember 4 is divided into an upper part 4 a and a lower part 4 b. Theupper part 4 a incorporates a male screw 4 c, and the lower part 4 bincorporates a female screw 4 d, so that the upper and lower partsrotate relatively to bring the seal members into press contact with eachother. The other seal member 5 is made rigid and united with the bagmember 10 similarly to the eighth embodiment.

FIG. 110 shows a fluid discharging device 7000 which is used after usingthe physical protector according to the embodiments mentioned above ofthe present invention.

The fluid discharging device 7000 is formed by a pair of case halves7002 connected to each other through a hinge 7003 like a cosmeticcompact. Between the case halves, a flat partition member 7001 isinterposed. The case half 7002 is formed by attaching a lid member 7005of soft synthetic resin to the outside of a frame 7004 of hard syntheticresin. By pressing the lid member 7005 in the state that the aforesaidphysical protector is placed between the partition member 7001 and thelid member 7005, the fluid G can be discharged acceleratedly.

The frame 7004 of the case half 7002 has a valve receiving portion 7006into which the valve a is inserted. In the lid member 7005 of the casehalf 7002, there is bored a fluid outlet hole 7007 for allowing thefluid G discharged from the valve a to escape outward. Each frame 7004of the case half 7002 has an engaging protrusion 7008, andcorrespondingly, the partition member 7001 has holes 7009 for receivingthe engaging protrusions 7008 of the frames, so that the case halves7002 and the partition member 7001 can be kept in their closed state.

According to this fluid discharging device 7000, the fluid G can bedischarged from the bag member 10 easily and promptly.

The physical protector of the invention can be applied to various fieldsand purposes other than those mentioned above by use of its cushioningand heat-retaining functions. To further heighten these functions, theremay be employed a material capable of emitting far infrared radiationand/or a mechanism using solar heat.

The various types of embodiments of the invention were described aboveon the assumption that expandable material is accommodated in the bagmember 10 in its compressed state, but this should not be understood aslimitative. The bag member 10 in which such expandable material is notaccommodated can be inflated by operating the valve a to introduce airthereinto through the pump portion or mouth portion. The discharge ofthe air can be carried out by opening the valve a and pressing the bagmember. Although the reinforcing member 30 is applied to some of theembodiments described above, it may be added to the bag member of theother embodiments if the need arises.

Also, the bag member 10 may be provided on its inner or outer side withdeformation-retaining means made of resin material which is deformedinto a fixed shape with body temperature. The resin material is what isknown as polymer jell, hydro jell, smart jell, and terminal jell. Theterminal jell assumes a fluid state at room temperature, but exhibitsviscosity to assume a fixed shape when warmed with body temperature.Thus, the deformation-retaining means can assist to protect and/or cureeach part of the human body.

As described above, since the physical protector according to thepresent invention comprises the inflatable bag member with a pluralityof seal members which are different in deformability, a two-way valvecapable of opening and closing due to the difference in deformability,which is remarkably made simple in structure and compact, can berealized. Also, since the protector makes use of the deformability ofthe seal members, an effect in that the protector is not embrittled normalfunctions during repeated prolonged use can be brought about.

Furthermore, since the expandable material accommodated in the bagmember can spontaneously expand to maintain its shape when opening thevalve, it can be controlled in degree of expansion by depressing thevalve, and therefore, suitably used as a physical protective means.Besides, the shape of the bag member thus expanded can be maintained andthe degree of expansion of the bag member can be regulated by operatingthe valve.

As described above, since the physical protector according to thisinvention has the seal members constituting a valve which is disposed ona flat bag member and elastically deformed with a depressing force toform an air passage between the seal members and regains its originalshape when releasing the depressing force to close the air passage, thebag member can conveniently be attached to an object to be protected andinflated with ease. Therefore, the physical protector can be applied forprotecting and/or securing each part of the human body such as the trunkand limbs in various medical situations, or used as a supporter,protector or corset for various sports, or packaging means capable ofeasily and reliably protecting goods or articles of various shapes otherthan the human body.
